lMPROVEMENTlN WATER-CLOSETS.

Specification forming part of Letters Patent No. 161,004, dated March23, 1875; application filed June 3, 1874.

To all whom it may concern:

Be it known that I, HENRY PHILIP BU- CHAN, of the town and county ofSouthampton, England, merchant, a subject of the Queen of Great Britain,have invented or discovered new and useful Improvements inWater-Glosets; and I, the said HENRY PHILIP BUCHAN, do hereby declarethe nature of the said invention, and in What manner the same is to beperformed, to be particularly described and ascertained in and by thefollowing statement thereofthat is to say:-

This invention has for its object to apply disinfecting-fluid towater-closets. The apparatus used for this purpose can be fixed eitherabove or below the seat of the closet, and is connected with a reservoircontaining the disinfecting-fluid. It consists of a small cylinder ofsufficient capacity to hold enough disinfecting'fluid to destroy allnoxious gases and organic matter at each use of the closet.

At the two ends of the cylinder are two taps, so arranged that when onetap is shut the other is open, and vice versa. On the plug of each tapis a lever, and the two are connected with an iron rod, which is coupledto the handle or lever of the closet, so that when the handle is liftedto empty the contents of the pan one tap is opened to allow thedisinfecting-fluid from the reservoir to fill the cylinder,but the othertap is shut, so that it cannot escape. When the handle is let down thereverse action takes place, and the 'fluid in the cylinder isdischarged, and conducted, by a small pipe, to the pan-valve, trap, ordrain. An airpipe is provided at the top of the cylinder to allow theair to escape while it is being filled with the fluid.

In order that my invention may be fully understood and readily carriedinto effect, I have shown in the drawings hereunto annexed an apparatusconstructed according to my invention, for supplying disinfecting-fluidto waterclosets.

I Figure 1 of the drawings shows a front view of the apparatus; and Fig.2, an end-view of the same, together with so much of the ordinaryseat-pan and pull-up apparatus of a water-closet as is necessary toexplain its action.

In these figures, A is the small cylinder or vessel 5 B B, two taps, oneat each end of the cylinder. On the plug of each tap is a leverarm,jointed to a connecting-rod, C. At the center of this rod is carried apin, D, which is connected, by the connecting-rod E, with a crank, F,and this crank is connected, by the rod G, to the lever by which thepan-valve is opened and closed, and to which the ordinary pull-up handleis connected. By this means, when the handle of the closet is raised,the tap B is opened and the tap B closed, and when the handle is loweredthe position of the taps is reversed. From the tap B a pipe, K, passesto the bottom of a small supply-cistern, H, containing a supply ofdisinfecting-fluid, so that when the tap B is opened the cylinder Afills with disinfecting-fluid, there being an airpipe, A, rising up fromthe cylinder, to allow air to escape from it, and this pipe is turnedover at its upper end to overhang the cistern H, so that any liquidrising up it quickly may, if jerked out from its upper end, be receivedback again into the tank. From the tap B a pipe, L, passes to the panofthe closet or in to the end of the water-supply pipe. The cistern,together with the cylinder A, and the taps, levers, and rods, areinclosed in a wooden casing, (not shown in the drawing,) and this casingis constructed so that any part of the apparatus can be readily got at.

The action of the apparatus is as follows: When the apparatus is atrest-that is, before the closet is usedthe tap B is closed, so that nofluid comes into the cylinder from the cistern H. When the handle of thecloset is raised, the tap B is closed and the tap B opened. The cylinderA and air-pipe, rising from it, then become filled with liquid, when thehandle is again lowered, the tap 'B is opened, and the tap B closed. Thedisinfecting-fluid in the cylinder A and air-pipe then fiows,bygravitation, through the pipe L, into the pan of the closet.

A sectional view, taken through the plugs of the two taps B B in theirtwo positions, is shown at Fig. 3.

Having thus described the nature of my invention, and the manner ofperforming the same, I would state that I do not confine myself to theprecise construction of the apparatus as shown in the drawings hereuntoannexed, as various modifications may be made in its construction, as,for example, the cylinder A, in place of being mounted horizontally,

. may be mounted vertically, and the taps at cylinder and water-closet,and lever-connections between the taps and pull-up handle of thewater-closet, whereby the disinfecting-fl uid is shut 011' as the handleof the closet is raised to let on the water, and discharged when theWater-supply is shut ofi.

2. The combination, substantially as hereinbefore set forth, of thereservoir, cylinder, the taps, their lever-connections, and the airpipeof the cylinder, whereby the capacity of the cylinder is increased, andthe quick discharge of the fluid secured.
